推荐答案

DoEvents是一种权宜之计，可使其更容易从UI线程中产生，以便进行绘制可能发生.基本上，由于线程是一个复杂的主题(在引入它的经典VB版本中实际上是不可能的)，因此DoEvents允许UI在执行其他语言要求您委派给其他线程以保持UI的处理时保持响应性响应.

DoEvents is provided as a stopgap measure to make it easier to yield from the UI thread so that painting can occur. Basically, as threading is a complicated topic (and was effectively impossible in the version of classic VB it was introduced in), DoEvents allows the UI to remain responsive while performing processing that other languages would require you to delegate to other threads to keep the UI responsive.
